Turbulent Drag Reduction by Surfactant Additives

Turbulent drag reduction by additives has long been a hot researchtopic. This phenomenon is inherently associated with multifoldexpertise. Solutions of drag-reducing additives are usuallyviscoelastic fluids having complicated rheological properties.Exploring the characteristics of drag-reduced turbulent flows callsfor uniquely designed experimental and numerical simulationtechniques and elaborate theoretical considerations. Pertinentlyunderstanding the turbulent drag reduction mechanism necessitiesmastering the fundamentals of turbulence and establishing a properrelationship between turbulence and the rheological propertiesinduced by additives. Promoting the applications of the dragreduction phenomenon requires the knowledge from different fieldssuch as chemical engineering, mechanical engineering, municipalengineering, and so on. This book gives a thorough elucidation ofthe turbulence characteristics and rheological behaviors, theories,special techniques and application issues for drag-reducing flowsby surfactant additives based on the state-of-the-art of scientificresearch results through the latest experimental studies, numericalsimulations and theoretical analyses. Covers turbulent drag reduction, heat transfer reduction,complex rheology and the real-world applications of dragreduction Introduces advanced testing techniques, such as PIV, LDA, andtheir applications in current experiments, illustrated withmultiple diagrams and equations Real-world examples of the topic’s increasingly importantindustrial applications enable readers to implement cost- andenergy-saving measures Explains the tools before presenting the research results, togive readers coverage of the subject from both theoretical andexperimental viewpoints Consolidates interdisciplinary information on turbulent dragreduction by additives Turbulent Drag Reduction by Surfactant Additives isgeared for researchers, graduate students, and engineers in thefields of Fluid Mechanics, Mechanical Engineering, Turbulence,Chemical Engineering, Municipal Engineering. Researchers andpractitioners involved in the fields of Flow Control, Chemistry,Computational Fluid Dynamics, Experimental Fluid Dynamics, andRheology will also find this book to be a much-needed reference onthe topic.
